Hawaii was surrounded by waters with warmer-than-average sea surface temperatures on 9 September 2019. Departures from the seasonal norm are shown in degrees Celsius. On this date, Lihue, Kauai observed its 17th consecutive day of a daily record high temperature being set or tied. This is likely the longest such stretch for any official weather station with a long period of record (more than 50 years) at any site in the U.S. climate database. Graphic: Tropical Tidbits

Hawaii’s warmest summer on record and Alaska’s second warmest in 2019

Extreme ice smasher storm headed for the Arctic, two months early

By Tyler Hamilton 21 August 2019 (The Weather Network) – This storm is about two months early for the Arctic. Later this week a rare system will make its way into the Arctic Ocean. This system’s pressure centre is expected to dip to an unusually low value for the month of August. Just how low? […]

Nutrient loading lowers resistance to thermal stress in Florida Keys corals – “These data make clear that this is not an ‘either temperature or nutrients’ situation, but rather a ‘both/and’ combination of multiple stressors”

By Gisele Galoustian 15 July 2019 (FAU) – Coral reefs are considered one of the most threatened ecosystems on the planet and are dying at alarming rates around the world. Scientists attribute coral bleaching and ultimately massive coral death to a number of environmental stressors, in particular, warming water temperatures due to climate change. A […]

Hurtigruten’s cruise ship MS Roald Amundsen is seen in the sea near Ulsteinvik, Norway, on 1 July 2019. The Roald Amundsen is the world’s first cruise ship propelled partially by battery power and is set to head out from northern Norway on its maiden voyage, cruise operator Hurtigruten said on Monday. The hybrid expedition cruise ship can take 500 passengers and is designed to sail in harsh climate waters. Named after the Norwegian explorer who navigated the Northwest Passage in 1903-1906 and was first to reach the South Pole in 1911, the ship heads for the Arctic from Tromsø this week and will sail the Northwest Passage to Alaska before heading south, reaching Antarctica in October 2019.
